Summary

Magnetic resonance (MR) imaging, including MR cholangiography, effectively diagnosed Mirizzi syndrome in three patients. This technique identified bile duct dilation, gallstones, and gallbladder wall changes, proving useful for diagnosis.

Area of Science:

  • Radiology
  • Gastroenterology
  • Medical Imaging

Background:

  • Mirizzi syndrome is a rare complication of gallstones.
  • Accurate diagnosis is crucial for appropriate management.
  • Magnetic resonance (MR) imaging offers detailed visualization of biliary anatomy.

Observation:

  • Three cases of Mirizzi syndrome were diagnosed using MR imaging.
  • MR cholangiography demonstrated intrahepatic bile duct dilation and common hepatic duct narrowing.
  • Gallstone location in the cystic duct and gallbladder wall thickening with enhancement were identified.

Findings:

  • MR imaging, particularly with MR cholangiography sequences, accurately depicted the key features of Mirizzi syndrome.
  • The study highlights the utility of MR in delineating biliary obstruction and gallstone impaction.

  • Characteristic gallbladder wall changes were also visualized.

    • Implications:

    • MR imaging is a valuable non-invasive tool for diagnosing Mirizzi syndrome.
    • Improved diagnostic accuracy can lead to timely and effective treatment strategies.
    • This imaging modality aids in understanding the complex anatomical changes associated with the syndrome.
